Specification of 'Letters Patent.

Application filed April 5, 1969. Serial No. 487,873.

To all fu/iomflt ymay concern.'

lie it known that I, CHARLES C. BALL, a citizen of th'e United States of America, re-

I siding in Newark, in the county or' Essen t out. iinpairing the strength of the post.

'lhc invention consists of a post `for link buttons which is bent up from a longitndiw nal blank of sI1cetj.-nictal provided with inclincd arnis which forni the braces between 'the legs ot' the Vsshaped post, and which arc integral with one leg of the post and attached to the other leg, the legs and braces being bent up troni the blank, as will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings', Figure l represents a front-view of a link-button with iny improved post, Fig. 2 is a sideview oi' the saine, lilig. 3 is a top-view of the blank of sheet-metal from which `the post is -to be made, Fig. l is a vertical transverse section on line t, 4, Fig. 3, Fig. is a topview o1 thc blank at'ter the saine is bent into U or chainici-shape, Fig'. t5 is a detail sideview of Fig. 5, Figa-7 is a'vertical transverse section on line 7, 7, Fig. 6, Fig. 8 is a side-view of the post bent into V-shape from l the channeled blank shown in Figs. 6 and 7,

and Fig, 9 is a side-view of the finished post ready t'or applying the buttons.'

Similar letters of reference indicate cor responding parts throughout the different figures. l VReferring to the drawings, a represents my' improved post for link-buttons. The post o has the general shape and appearance of the well-known solid posts heretofore in use, but dit'ers from them by being hollow that is to say by being bentup from ablank a?, which is made of a flat longitudinal Strip of sheet-metal and provided about midway with short recesses a2 at opposite sides and near one end with inclined arms a, which form the brace for the legs of the post when the blank is bent up into proper shape.

The blank (il is cut from sheet-metal of suitable thickness by suitable punching dies and then bent up by shaping dies into U- shaped cross-section, as shown in Figs. 5, 6 and 'i'. The lll-shaped or channeled blank is nextbentup into 'tf-shape, as shown in Fig. 8, so as to form a, extending upwardly from the recessed portionf, after which the arms a3 are soldered onto. the inner edges of the longer leguit. The nal curved shape is then given to the legs c* by suitable dies, shown in Fig. The U-shaped cross section `of the convcrginglegs of the post imparts considerable strength to the post which is equal if not stronger than a solid post. The ends ot the curved legs of the post'. are soldered to the uiulei.'side of the. larger button t), abutting against the underside of the riin oi? the same, while the apex of the post; is soldered to the centerof the smaller button 721. the arms c acting as braces :for connecting` the legs and impart the required strength to the saine, so that the required resistance to the strain to which Athe link-button is exposed is imparted thereto.

Having thus described my invention, l claini as new and desire to secure by Letters Patent:

l. `A post for link-buttons, made of V- shape of two bent-up legs of U-shaped crosssection. `united at the apex, and by braces` approximately at the middle-portion of the legs, said braces heilig bent up from one leg` and attached to the inner edges of the other leg.

2. A blank for the posts of link-buttons consisting of a. longitudinal strip of sheetmetal, recesses approximately at the middleportion of the. saine, and inclined arms at opposite sides near one end of the saine.

8. A l-shaped post for link-buttons made of' a single piece of sheet-metal of suitable thickness comprising two longitudinally curved bent 'up legs of U-shaped cross-section, a narrow connecting' strip holding the inner ends of said legs together and formed by recesses cutI in said pieces of sheetnietal, and laterally extending arms formed integral with one of said legs and rigidly se cured to the other leg.

4. A link-button Comprising a V-shaped post having bent up legs of Ushaped crosssection held together at theirinner ends b a narrmv-coiinecting strip integral with both of the legs, the intermediate part of. said legs Patented Dec. 258, 19409. n

being held together "by a pair Of laterally Tn testimony, that l claim the foregoing extending spaced legs integral with one of as my invention, I have signed my name in said legs und soldered to the other, a, small presence of two subscribing Witnesses.

button soldered to said inner ends and said ,i connecting strip, and a larger button to the Witnesses: diametrically opposite side of lle rim of PAUL GOEPEL, which the outer ends of saidlegs are secured. H. J. SUHRBIER. l
